“…In recent years, plasma antenna remains an extensive trend in the research of antenna than traditional metal antenna (Bonde et al, 2014). The disadvantages of the metal antenna are less efficient because the design of metal antenna is limited to its length, which affects its signal strength, and its higher weight compared to plasma antenna.…”

Plasma antenna is a type of radio antenna in which plasma is used instead of the metal elements of a traditional antenna. One of the advantages of using plasma antenna is it can improve conventional devices in terms of switching (on/off) the antenna using plasma generator, which could make it invisible to the radar. In addition, when antenna conductivity can be controlled through manipulation of plasma parameters, an adjustable antenna can be designed. The aims of this research are to design and simulate plasma antenna using CST software, and subsequently determine the characteristics of plasma antenna with different neon pressure applied (10, 15, 20 Torr). The custommade cylindrical discharge tube shape with the length and diameter of 160 mm and 10 mm was used. The research focuses on simulation in obtaining antenna parameters while conducting an experimental work to obtain electrical parameters which are needed in calculating the plasma parameters. The discharge tube shape was designed and simulated using Computer Simulation Technology (CST) that can generate antenna parameters such as return loss, gain, directivity and radiation pattern. The simulation result shows the radiation pattern of discharge tube as omni-directional and it gives neon discharge at 20 Torr that has the best performance in return loss at -24.490250 dB, compared to neon at 15 and 10 Torr which have lower values at -21.578 dB and -13.901 dB respectively. In terms of gain and directivity, neon at 10 Torr has the highest value, which is 2.688 dB and 5.437 dBi, respectively. From the results, it can be concluded that when gas pressure is increased, the antenna gains decreases. Neon discharge at a middle pressure of 15 Torr is considered to provide a good antenna gain and give effective signal transmission compared to lower pressure of 15 and higher pressure of 20 Torr.

“…Prevalent traditional antennas and other types of material based antenna such as dielectric resonators and metamaterials have been studied widely while there is the little study on plasma antennas [9][10][11][12][13]. It must be noted that most of the researches on plasma antenna parameters had done on the basic form of plasma antenna (plasma column) [14][15][16][17][18]. In [14] the return loss of a plasma monopole antenna with different radius and length are reported.…”

“…The return loss of cylindrical plasma antenna with different electron density is simulated and investigated in [15]. Sharan Bonde and et al studied plasma monopole antenna parameters with two different gases, argon and neon where radiation patterns and return losses of both structure were reported in [16]. In [17], Nur Aina Halili and et.al.…”

This study examines the effect of different pressures on the radiation characteristics of the loop-shaped plasma antenna filled by two gases; Argon and Nitrogen. Proposed loop plasma antennas operating at LTE and Wi-Fi frequency bands have been designed and its performance studied at three different pressures of 2.28, 5 and 10 Torr. The radiation characteristics of the both loop-shaped plasma antennas have been investigated and presented for three different pressures. To analyze the performance of the proposed antenna, full-wave simulation were run using the finite integral method software, CST Microwave Studio.
